152-566: The Trans-Canada Highway ( French : Route Transcanadienne ; abbreviated as the TCH or T-Can ) is a transcontinental federal–provincial highway system that travels through all ten provinces of Canada , from the Pacific Ocean on the west coast to the Atlantic Ocean on the east coast. The main route spans 7,476 km (4,645 mi) across the country, one of the longest routes of its type in

304-522: A concurrency or overlap. For example, I‑75 and I‑85 share the same roadway in Atlanta ; this 7.4-mile (11.9 km) section, called the Downtown Connector , is labeled both I‑75 and I‑85. Concurrencies between Interstate and US Highway numbers are also allowed in accordance with AASHTO policy, as long as the length of the concurrency is reasonable. In rare instances, two highway designations sharing

456-542: A 20-year effort to convert its entire 516 km (321 mi) section of the Trans-Canada Highway into a four-lane limited-access divided highway. The highway has a speed limit of 110 km/h (68 mph) on most of its sections in New Brunswick. New Brunswick was the first province where the main route of the Trans-Canada Highway was made entirely into a four-lane limited-access divided highway. From Moncton,

608-637: A 28-year-old brevet lieutenant colonel, accompanied the trip "through darkest America with truck and tank," as he later described it. Some roads in the West were a "succession of dust, ruts, pits, and holes." As the landmark 1916 law expired, new legislation was passed—the Federal Aid Highway Act of 1921 (Phipps Act). This new road construction initiative once again provided for federal matching funds for road construction and improvement, $ 75 million allocated annually. Moreover, this new legislation for

760-454: A 75-kilometre (47 mi) section from Whitbourne to St. John's are divided. Although there does not appear to be any nationally-sanctioned "starting point" for the entire Trans-Canada Highway system, St. John's has adopted this designation for the section of highway running in the city. The foot of East White Hills Road in St. John's, near Logy Bay Road , would be a more precise starting point of

912-476: A change in the numbering system as a result of a new policy adopted in 1973. Previously, letter-suffixed numbers were used for long spurs off primary routes; for example, western I‑84 was I‑80N, as it went north from I‑80 . The new policy stated, "No new divided numbers (such as I-35W and I-35E , etc.) shall be adopted." The new policy also recommended that existing divided numbers be eliminated as quickly as possible; however, an I-35W and I-35E still exist in

1064-751: A collective label for all these varieties, and Quebec French has also been used for the entire dialect group. The overwhelming majority of francophone Canadians speak this dialect. Acadian French is spoken by over 350,000 Acadians in parts of the Maritime Provinces , Newfoundland, the Magdalen Islands , the Lower North Shore and the Gaspé Peninsula . St. Marys Bay French is a variety of Acadian French spoken in Nova Scotia. Métis French

1216-453: A four-lane divided highway . Alberta, Saskatchewan, and Manitoba have widened most of their southern Trans-Canada Highway network to four lanes. In Quebec, most sections of the TCH network overlap with the province's Autoroute freeways. New Brunswick is the only province to have its whole length of the main Trans-Canada Highway route at a four-lane freeway standard. Like the former U.S. Route 66 ,

1368-800: A freeway and proceeds 206 km (128 mi) east to Montreal , as Highway 417 in Ontario (and the Queensway in Ottawa) and Autoroute 40 in Quebec. The Trans-Canada assumes the name Autoroute Métropolitaine (also known as "The Met" or "Metropolitan Boulevard") as it traverses Montreal as an elevated freeway. At the Laurentian interchange, in Montreal, the Abitibi route (Highway 66, Route 117, A-15) rejoins

1520-465: A junction just south of Rivière-du-Loup , 173 km (107 mi) northeast of Lévis . At that junction, the highway turns southeast and changes designation to Autoroute 85 for 43 km (27 mi), and then downgrades from a freeway to Route 185 , a non-Autoroute (not limited-access) standard highway until Saint-Louis-du-Ha! Ha! , where Autoroute 85 resumes once again. The portion from Autoroute 20 to Edmundston , New Brunswick,

1672-488: A lesser extent, Aroostook County , Maine, and Beauce of Quebec. Although superficially a phonological descendant of Acadian French, analysis reveals it is morphosyntactically identical to Quebec French. It is believed to have resulted from a localized levelling of contact dialects between Québécois and Acadian settlers . There are two main sub-varieties of Canadian French. Joual is an informal variety of French spoken in working-class neighbourhoods in Quebec. Chiac

1824-463: A maximum of 90 km/h (56 mph) in rural areas. The Trans-Canada Highway through the three prairie provinces is 1,667 km (1,036 mi) long. It starts at the border with British Columbia at Kicking Horse Pass, and runs all the way to the Ontario border at Whiteshell. The highway continues through Alberta, running east for 206 km (128 mi) as Alberta Highway 1 to Lake Louise , Banff , Canmore , and Calgary . This section of

1976-580: A national road grid with the passage of the Federal Aid Highway Act of 1921 . In 1926, the United States Numbered Highway System was established, creating the first national road numbering system for cross-country travel. The roads were state-funded and maintained, and there were few national standards for road design. United States Numbered Highways ranged from two-lane country roads to multi-lane freeways. After Dwight D. Eisenhower became president in 1953, his administration developed

2128-576: A numbering scheme in which primary Interstates are assigned one- or two-digit numbers, and shorter routes which branch off of longer ones are assigned three-digit numbers where the last two digits match the parent route. The Interstate Highway System is partially financed through the Highway Trust Fund , which itself is funded by a combination of a federal fuel tax and transfers from the Treasury's general fund. Though federal legislation initially banned

2280-481: A proposal for an interstate highway system, eventually resulting in the enactment of the Federal-Aid Highway Act of 1956 . Unlike the earlier United States Numbered Highway System, the interstates were designed to be all freeways, with nationally unified standards for construction and signage. While some older freeways were adopted into the system, most of the routes were completely new. In dense urban areas,

2432-465: A province (especially in Ontario and Quebec) as the TCH piggybacks along separate provincial highways (which often continue as non-TCH routes outside the designated sections) en route. In addition, Ontario and Quebec use standard provincial highway shields to number the highway within their boundaries, but post numberless Trans-Canada Highway shields alongside them to identify it. As the Trans-Canada route

2584-540: A report called Toll Roads and Free Roads , "the first formal description of what became the Interstate Highway System" and, in 1944, the similarly themed Interregional Highways . The Interstate Highway System gained a champion in President Dwight D. Eisenhower, who was influenced by his experiences as a young Army officer crossing the country in the 1919 Motor Transport Corps convoy that drove in part on

2736-621: A signalized four-lane arterial road for short stretches in Salmon Arm , Revelstoke , and Golden , but has no signal lights on it for most of its length. The highway crosses two high passes along its route: Rogers Pass in Glacier National Park , and Kicking Horse Pass in Yoho National Park . At Kicking Horse Pass, the highest point on the whole Trans-Canada Highway system is reached, at 1,627 m (5,338 ft). Speed limits on

2888-409: A single digit prefixed to the two-digit number of its parent Interstate Highway. Spur routes deviate from their parent and do not return; these are given an odd first digit. Circumferential and radial loop routes return to the parent, and are given an even first digit. Unlike primary Interstates, three-digit Interstates are signed as either east–west or north–south, depending on the general orientation of

3040-663: A small arterial road , it enters the Departure Bay Terminal and crosses the Strait of Georgia to Horseshoe Bay via BC Ferries . From there, it travels through Metro Vancouver on a four-to-eight-lane freeway before leaving the city and continuing as a four-lane freeway eastward up the Fraser Valley to Hope . There, the Trans-Canada Highway exits the freeway and turns north for 186 km (116 mi) through Fraser Canyon and Thompson Canyon toward Cache Creek , mostly as

3192-769: A speed limit of 45 mph (70 km/h) because it is a parkway that consists of only one lane per side of the highway. On the other hand, Interstates 15, 80, 84, and 215 in Utah have speed limits as high as 70 mph (115 km/h) within the Wasatch Front , Cedar City , and St. George areas, and I-25 in New Mexico within the Santa Fe and Las Vegas areas along with I-20 in Texas along Odessa and Midland and I-29 in North Dakota along

3344-456: A speed limit of 80 mph (130 km/h). Other Interstates in Idaho, Montana, Oklahoma, South Dakota and Wyoming also have the same high speed limits. In some areas, speed limits on Interstates can be significantly lower in areas where they traverse significantly hazardous areas. The maximum speed limit on I-90 is 50 mph (80 km/h) in downtown Cleveland because of two sharp curves with

3496-467: A suggested limit of 35 mph (55 km/h) in a heavily congested area; I-70 through Wheeling, West Virginia , has a maximum speed limit of 45 mph (70 km/h) through the Wheeling Tunnel and most of downtown Wheeling; and I-68 has a maximum speed limit of 40 mph (65 km/h) through Cumberland, Maryland , because of multiple hazards including sharp curves and narrow lanes through

3648-410: A tourism and travel centre. The Coquihalla project also realigned Highway 1 (TCH) to a new freeway bypass around Kamloops . Plans for a freeway to bypass or eliminate traffic congestion and road hazards along the heavily-travelled route from Victoria to Nanaimo on Vancouver Island were cancelled during the recession that followed the 1987 stock market crash . In Alberta, between 1964 and 1972,

3800-450: A two-lane route, portions of the route are built as two-lane expressways . Two short bypasses are also considered part of the Trans-Canada Highway system. These include the 42-kilometre-long (26 mi) Perimeter Highway 100 bypass around Winnipeg, which provides an expressway standard alternative to the crowded Highway 1 in the city centre, and the 34-kilometre-long (21 mi) two-lane Kenora Bypass ( Highway 17A ), which

3952-473: A two-lane rural highway with only occasional traffic lights. Approaching Kamloops , Highway 1 re-enters a short freeway alignment (briefly concurrent with Highways 5 and 97 ), before passing through Kamloops itself as a four-lane signalized highway. From Kamloops, the highway continues east as a mostly-two-lane rural highway through the Interior of British Columbia, with occasional passing lanes. It widens to

4104-535: Is 1,045 km (649 mi) long, beginning in Victoria at the intersection of Douglas Street and Dallas Road (where the "Mile 0" plaque stands), and ending on the Alberta border at Kicking Horse Pass . The highway starts by passing northward along the east coast of Vancouver Island for 99 km (62 mi) to Nanaimo along a mostly-four-lane, heavily-signalized highway. After passing through downtown Nanaimo on

4256-413: Is a blending of Acadian French syntax and vocabulary, with numerous lexical borrowings from English. The term "Canadian French" was formerly used to refer specifically to Quebec French and the closely related varieties of Ontario and Western Canada descended from it. This is presumably because Canada and Acadia were distinct parts of New France , and also of British North America , until 1867. The term

4408-470: Is a two-lane route that bypasses the entire town to the north. Early on, much of the route of the Trans-Canada Highway was first explored in order to construct the Canadian Pacific Railway in the late 19th century, a route which much of the mainline TCH route later ended up following. The Trans-Canada Highway was not the first road across Canada. In British Columbia, the highway was predated by

4560-534: Is also commonly believed the Interstate Highway System was built for the sole purpose of evacuating cities in the event of nuclear warfare . While military motivations were present, the primary motivations were civilian. The numbering scheme for the Interstate Highway System was developed in 1957 by the American Association of State Highway and Transportation Officials (AASHTO). The association's present numbering policy dates back to August 10, 1973. Within

4712-419: Is approximately 120 km (75 mi) long. Since the Trans-Canada Highway for the most part follows Quebec's Autoroute System, which is always composed of a minimum four-lane freeway, travel through Quebec is generally, safe, fast, and congestion-free. The exception is the route through Montreal, which can be prone to traffic congestion. However, drivers can bypass the city on the tolled Autoroute 30, which

4864-437: Is designated as Highway 16 in all four provinces that it passes through (British Columbia, Alberta, Saskatchewan, and Manitoba). It follows a more northerly east–west route across Western Canada than the main TCH and passes through fewer cities, with Edmonton being the largest on the route. Other major municipalities on the route include Prince Rupert , Prince George , Lloydminster , and Saskatoon . The Yellowhead Highway

5016-465: Is largely non-functional as a major long distance corridor due to its roundabout route and the complete avoidance of the Toronto area. It is a 671-kilometre-long (417 mi) alternate route to Highway 17 (the mainline TCH) between Sudbury and Ottawa. It passes through several major communities, including Orillia and Peterborough . Because it passes closer to major population centres, this section of

5168-461: Is limited to 110 km/h (68 mph), but is 100 km/h (62 mph) east of Winnipeg. East of Winnipeg, the highway continues for over 200 km (120 mi) to Kenora , Ontario. At the provincial border, the expressway becomes an arterial highway, and the numeric designation of the highway changes from 1 to 17. It is signed with a provincial shield along with a numberless Trans-Canada Highway sign, and continues as an arterial highway along

5320-584: Is most well-known for passing through Jasper National Park in Alberta, where it crosses the Continental Divide through its namesake Yellowhead Pass . Since it carries significantly less traffic than its more southerly counterpart, the Yellowhead is almost exclusively a two-lane highway in British Columbia and Manitoba, and is only partially a four-lane expressway in Alberta and Saskatchewan. Until 1990,

5472-520: Is no longer usually deemed to exclude Acadian French. Phylogenetically , Quebec French, Métis French and Brayon French are representatives of koiné French in the Americas whereas Acadian French, Cajun French, and Newfoundland French are derivatives of non-koiné local dialects in France. The term anglicism ( anglicisme ) is related to the linguistic concepts of loanwords , barbarism , diglossia , and

5624-645: Is not part of the Trans-Canada. The maximum speed limit on the Quebec Autoroute System (including the TCH) is a strictly-enforced 100 km/h (62 mph). However, the speed limit may be lower in select spots, such as through tunnels or major interchanges. Since 2018, Quebec has been working on upgrading the 40-kilometre-long (25 mi) two-lane section of Trans-Canada Highway along Route 185 to an Autoroute, with 21.5 km (13.4 mi) of new freeway commissioned during 2021–22, another 10 km in 2024 and

5776-604: Is notable that the Trans-Canada largely bypasses Canada's most heavily populated region, the Golden Horseshoe area of Southern Ontario, which includes Canada's largest city, Toronto . However, a short section of the Central Ontario branch does pass through the rural northeastern edge of Durham Region at both Sunderland and Beaverton, which is officially part of the Greater Toronto Area. Access to Toronto itself from

5928-476: Is part of the Trans-Canada Highway system, and bypasses the city with a mix of traffic lights and interchanges, while Highway 1 continues through central Winnipeg as a signalized arterial road. With the exception of a 15.3-kilometre-long (9.5 mi) stretch of two-lane highway just west of the Ontario border, the entire length of Highway 1 through the Prairie Provinces is a four-lane highway. While

6080-567: Is part of the Trans-Canada Highway system, but is almost exclusively referred to as the Yellowhead Highway and is often recognized as its own highway under that name. In comparison, Highway 1 in Western Canada is always referred to as the Trans-Canada Highway, and has a significantly higher traffic volume with a route passing through more major cities than the less important Highway 16 (Yellowhead) TCH route. Therefore Highway 1

6232-517: Is spoken in Manitoba and Western Canada by the Métis , descendants of First Nations mothers and voyageur fathers during the fur trade . Many Métis spoke Cree in addition to French, and over the years they developed a unique mixed language called Michif by combining Métis French nouns, numerals, articles and adjectives with Cree verbs, demonstratives , postpositions , interrogatives and pronouns.

The planned I-11 will then bridge the Interstate gap between Phoenix, Arizona and Las Vegas, Nevada , and thus form part of the CANAMEX Corridor (along with I-19 , and portions of I-10 and I-15 ) between Sonora , Mexico and Alberta , Canada. Political opposition from residents canceled many freeway projects around

6688-579: Is usually considered to be part of the main Trans-Canada Highway route, while Highway 16 is not, although it may be considered a second mainline corridor as it serves a more northerly belt of major cities, as well as having its own Pacific terminus. Although the TCH network is strictly a transcontinental system, and does not enter any of Canada's three northern territories or run to the United States border , it does form part of Canada's overall National Highway System (NHS), which provides connections to

6840-470: The Canadian Shield , a rugged, forested area with thousands of lakes. There are many cottage communities along this section of the Trans-Canada Highway, some of which have their driveways directly onto the highway. Highway 11/Highway 17 proceeds southeast for 65 km (40 mi) to Thunder Bay , then northeast for 115 km (71 mi) to Nipigon . An 83-kilometre (52 mi) segment of

6992-670: The Coquihalla Highway in 1986, the Trans-Canada Highway through the Fraser Canyon received less traffic, because the freeway bypass shortened the drive between Hope and Kamloops by 90 minutes. However, the route was retained as part of the Trans-Canada Highway system, and is considered a scenic route and a valuable part of the Fraser Country Circle Tour. The opening of the Coquihalla was also an economic disaster for many of

7144-705: The Crowsnest Highway , the Big Bend Highway , and the Cariboo Highway , all of which were constructed during the Great Depression era. Many of the earlier highways in British Columbia were largely gravel and had many frequent inland ferry crossings at wide rivers and lakes. In Alberta, the section between Calgary and Banff was predated by the Morley Trail (now Highway 1A), which was driveable starting in

7296-474: The Dallas–Fort Worth metroplex in Texas, and an I-35W and I-35E that run through Minneapolis and Saint Paul , Minnesota, still exist. Additionally, due to Congressional requirements, three sections of I-69 in southern Texas will be divided into I-69W , I-69E , and I-69C (for Central). AASHTO policy allows dual numbering to provide continuity between major control points. This is referred to as

Each Interstate Highway was required to be a freeway with at least four lanes and no at-grade crossings. The publication in 1955 of the General Location of National System of Interstate Highways , informally known as the Yellow Book , mapped out what became

As one of the components of the National Highway System , Interstate Highways improve the mobility of military troops to and from airports, seaports, rail terminals, and other military bases. Interstate Highways also connect to other roads that are a part of the Strategic Highway Network , a system of roads identified as critical to

7752-772: The Interstate Highway System , or the Eisenhower Interstate System , is a network of controlled-access highways that forms part of the National Highway System in the United States . The system extends throughout the contiguous United States and has routes in Hawaii , Alaska , and Puerto Rico . In the 20th century, the United States Congress began funding roadways through the Federal Aid Road Act of 1916 , and started an effort to construct

He recalled that, "The old convoy had started me thinking about good two-lane highways... the wisdom of broader ribbons across our land." Eisenhower also gained an appreciation of the Reichsautobahn system, the first "national" implementation of modern Germany's Autobahn network, as a necessary component of a national defense system while he

An option for maximizing traffic throughput on a highway is to reverse the flow of traffic on one side of a divider so that all lanes become outbound lanes. This procedure, known as contraflow lane reversal , has been employed several times for hurricane evacuations. After public outcry regarding

This numbering system usually holds true even if the local direction of the route does not match the compass directions. Numbers divisible by five are intended to be major arteries among the primary routes, carrying traffic long distances. Primary north–south Interstates increase in number from I-5 between Canada and Mexico along

Major west–east arterial Interstates increase in number from I-10 between Santa Monica, California , and Jacksonville, Florida , to I-90 between Seattle, Washington , and Boston, Massachusetts , with two exceptions. There are no I-50 and I-60, as routes with those numbers would likely pass through states that currently have US Highways with

Southeast of Amherst, near Thomson Station , the highway traverses the Cobequid Pass , a 45-kilometre (28 mi) tolled section ending at Masstown , before passing by Truro , where it links with Highway 102 to Halifax, 117 km (73 mi) east of

10184-401: The New Brunswick border. Halifax , like Toronto, is a provincial capital that the Trans-Canada Highway does not pass through. Beyond Truro, the highway continues east for 57 km (35 mi) to New Glasgow, where it meets Highway 106 , before continuing to the Canso Causeway , which crosses the Strait of Canso onto Cape Breton Island near Port Hawkesbury . From the Canso Causeway,

Marie , the highway crosses the Montreal River Hill , which sometimes becomes a bottleneck on the system in

11096-575: The Trans-Canada Highway was completely rerouted from its former two-lane alignment along the Bow River to a new, more direct, four-lane freeway between Banff and Calgary, resulting in the bypassing of several towns, such as Canmore . Prior to this change, one of the first traffic circles in Canada existed on Highway 1 at the "gateway" junction for Banff from at least as early as the 1950s. The current interchange on Highway 1 for Banff Avenue now occupies

11248-820: The US to determine the difficulties that military vehicles would have on a cross-country trip. Leaving from the Ellipse near the White House on July 7, the Motor Transport Corps convoy needed 62 days to drive 3,200 miles (5,100 km) on the Lincoln Highway to the Presidio of San Francisco along the Golden Gate . The convoy suffered many setbacks and problems on the route, such as poor-quality bridges, broken crankshafts, and engines clogged with desert sand. Dwight Eisenhower , then

11400-703: The United States, including: In addition to cancellations, removals of freeways are planned: The American Association of State Highway and Transportation Officials (AASHTO) has defined a set of standards that all new Interstates must meet unless a waiver from the Federal Highway Administration (FHWA) is obtained. One almost absolute standard is the controlled access nature of the roads. With few exceptions , traffic lights (and cross traffic in general) are limited to toll booths and ramp meters (metered flow control for lane merging during rush hour ). Being freeways , Interstate Highways usually have

11552-473: The Yellowhead Highway had its own unique highway number signs, but they have now mostly been replaced with standard maple-leaf Trans-Canada Highway signs, with numberless Yellowhead shields posted adjacent to them. The 1,547-kilometre (961 mi) section of Highway 71 and Highway 11 between Kenora and North Bay, Ontario , is considered part of the Trans-Canada Highway. This highway first runs south of

11704-473: The act was signed, and paving started September 26, 1956. The state marked its portion of I-70 as the first project in the United States completed under the provisions of the new Federal-Aid Highway Act of 1956. The Pennsylvania Turnpike could also be considered one of the first Interstate Highways, and is nicknamed "Grandfather of the Interstate System". On October 1, 1940, 162 miles (261 km) of

11856-648: The cancellation of the Somerset Freeway . This situation was remedied when the construction of the Pennsylvania Turnpike/Interstate 95 Interchange Project started in 2010 and partially opened on September 22, 2018, which was already enough to fill the gap. However, I-70 remains discontinuous in Pennsylvania , because of the lack of a direct interchange with the Pennsylvania Turnpike at

12008-406: The choice of routing destroyed many well-established neighborhoods, often intentionally as part of a program of " urban renewal ". In the two decades following the 1956 Highway Act, the construction of the freeways displaced one million people, and as a result of the many freeway revolts during this era, several planned Interstates were abandoned or re-routed to avoid urban cores. Construction of

12160-529: The city of Regina , and skirts around the city on the Regina Bypass , the most expensive infrastructure project in Saskatchewan to date. Beyond Regina, it continues east for 486 km (302 mi), across the border with Manitoba, to the cities of Brandon and Portage la Prairie , and finally 84 km (52 mi) east to Winnipeg . The southern portion of Winnipeg's Perimeter Highway (Highway 100)

12312-569: The city on Highway 417, which is between six and eight lanes wide at this point. In Southern Ontario , the speed limit is generally 80 km/h (50 mph) on the Trans-Canada, while in Northern Ontario it is 90 km/h (56 mph). Sections routed along Highway 417 outside urban Ottawa feature a higher limit of 110 km/h (68 mph). While Highways 17 and 417 are largely free from traffic congestion except for minor rush hour delays on Ottawa's stretch of Highway 417,

12464-517: The city. Ontario plans to eventually extend the 417 freeway to Sudbury, which will widen the section of the mainline TCH between Ottawa and Sudbury to four-lane freeway standards. However, there is no funding secured for such a project, as Ontario is currently focusing on extending Highway 400 to Sudbury along the Highway ;69 corridor (which is part of the Georgian Bay TCH route). It

12616-650: The city. In some locations, low speed limits are the result of lawsuits and resident demands; after holding up the completion of I-35E in St. Paul, Minnesota , for nearly 30 years in the courts, residents along the stretch of the freeway from the southern city limit to downtown successfully lobbied for a 45 mph (70 km/h) speed limit in addition to a prohibition on any vehicle weighing more than 9,000 pounds (4,100 kg) gross vehicle weight . I-93 in Franconia Notch State Park in northern New Hampshire has

12768-401: The collection of tolls, some Interstate routes are toll roads , either because they were grandfathered into the system or because subsequent legislation has allowed for tolling of Interstates in some cases. As of 2022 , about one quarter of all vehicle miles driven in the country used the Interstate Highway System, which has a total length of 48,890 miles (78,680 km). In 2022 and 2023,

12920-497: The construction and improvement of highways. The nation's revenue needs associated with World War I prevented any significant implementation of this policy, which expired in 1921. In December 1918, E. J. Mehren, a civil engineer and the editor of Engineering News-Record , presented his "A Suggested National Highway Policy and Plan" during a gathering of the State Highway Officials and Highway Industries Association at

13072-407: The contiguous United States, primary Interstates—also called main line Interstates or two-digit Interstates—are assigned numbers less than 100. While numerous exceptions do exist, there is a general scheme for numbering Interstates. Primary Interstates are assigned one- or two-digit numbers, while shorter routes (such as spurs, loops, and short connecting roads) are assigned three-digit numbers where

13224-566: The designation of Highway 1 and runs northeast for 219 km (136 mi) through Corner Brook , east for another 352 km (219 mi) through Gander , and finally ends at St. John's , another 334 km (208 mi) southeast, for a total of 905 km (562 mi), crossing the island. The majority of the Trans-Canada Highway in Newfoundland is undivided, though sections in Corner Brook, Grand Falls-Windsor , Glovertown , and

13376-618: The discontinuity, but they have been blocked by local opposition, fearing a loss of business. The Interstate Highway System has been expanded numerous times. The expansions have both created new designations and extended existing designations. For example, I-49 , added to the system in the 1980s as a freeway in Louisiana , was designated as an expansion corridor, and FHWA approved the expanded route north from Lafayette, Louisiana , to Kansas City, Missouri . The freeway exists today as separate completed segments, with segments under construction or in

13528-448: The dissemination of public information. As a result, the 2005 evacuation of New Orleans, Louisiana, prior to Hurricane Katrina ran much more smoothly. According to urban legend , early regulations required that one out of every five miles of the Interstate Highway System must be built straight and flat, so as to be usable by aircraft during times of war. There is no evidence of this rule being included in any Interstate legislation. It

13680-492: The eastern end of the concurrency near Breezewood . Traveling in either direction, I-70 traffic must exit the freeway and use a short stretch of US 30 (which includes a number of roadside services) to rejoin I-70. The interchange was not originally built because of a legacy federal funding rule, since relaxed, which restricted the use of federal funds to improve roads financed with tolls. Solutions have been proposed to eliminate

13832-450: The economy. Not just as a public works measure, but for future growth. Clay's committee proposed a 10-year, $ 100 billion program ($ 1.13 trillion in 2023), which would build 40,000 miles (64,000 km) of divided highways linking all American cities with a population of greater than 50,000. Eisenhower initially preferred a system consisting of toll roads , but Clay convinced Eisenhower that toll roads were not feasible outside of

13984-488: The existing, largely non-freeway, United States Numbered Highways system. By the late 1930s, planning had expanded to a system of new superhighways. In 1938, President Franklin D. Roosevelt gave Thomas MacDonald , chief at the Bureau of Public Roads, a hand-drawn map of the United States marked with eight superhighway corridors for study. In 1939, Bureau of Public Roads Division of Information chief Herbert S. Fairbank wrote

14136-426: The federal government, Interstate Highways are owned by the state in which they were built. With few exceptions , all Interstates must meet specific standards , such as having controlled access, physical barriers or median strips between lanes of oncoming traffic, breakdown lanes , avoiding at-grade intersections , no traffic lights , and complying with federal traffic sign specifications. Interstate Highways use

14288-462: The first three contracts under the new program were signed in Missouri on August 2, 1956. The first contract signed was for upgrading a section of US Route 66 to what is now designated Interstate 44 . On August 13, 1956, work began on US 40 (now I-70) in St. Charles County. Kansas claims that it was the first to start paving after the act was signed. Preliminary construction had taken place before

14440-594: The first time sought to target these funds to the construction of a national road grid of interconnected "primary highways", setting up cooperation among the various state highway planning boards. The Bureau of Public Roads asked the Army to provide a list of roads that it considered necessary for national defense. In 1922, General John J. Pershing , former head of the American Expeditionary Force in Europe during

14592-542: The highest speed limits in a given area. Speed limits are determined by individual states. From 1975 to 1986, the maximum speed limit on any highway in the United States was 55 miles per hour (90 km/h), in accordance with federal law. Typically, lower limits are established in Northeastern and coastal states, while higher speed limits are established in inland states west of the Mississippi River . For example,

14744-542: The highly populated coastal regions. In February 1955, Eisenhower forwarded Clay's proposal to Congress. The bill quickly won approval in the Senate, but House Democrats objected to the use of public bonds as the means to finance construction. Eisenhower and the House Democrats agreed to instead finance the system through the Highway Trust Fund , which itself would be funded by a gasoline tax. In June 1956, Eisenhower signed

14896-705: The highway (again signed exclusively with the TCH shield) follows the Saint John River Valley, running south for 170 km (110 mi) to Woodstock (parallelling the Canada–US border ) and then east for another 102 km (63 mi) to pass through Fredericton . 40 km (25 mi) east of Fredericton, the Saint John River turns south, whereby the highway crosses the river at Jemseg and continues heading east to Moncton another 135 km (84 mi) later. On November 1, 2007, New Brunswick completed

15048-503: The highway continues east, now designated as Highway 105 on Cape Breton Island, until reaching the Marine Atlantic ferry terminal at North Sydney . From North Sydney, a 177-kilometre (110 mi) ferry route, operated by the Crown corporation Marine Atlantic , continues the highway to Newfoundland , arriving at Channel-Port aux Basques , whereby the Trans-Canada Highway assumes

15200-569: The highway continues southeast for 54 km (34 mi) to a junction at Aulac close to the New Brunswick– Nova Scotia border (near Sackville ). Here, Trans-Canada Highway again splits into two routes, with the main route continuing to the nearby border with Nova Scotia as Route 2, and a 70-kilometre (43 mi) route designated as Route 16 , which runs east to the Confederation Bridge at Cape Jourimain . From

15352-607: The highway now designated I‑70 and I‑76 opened between Irwin and Carlisle . The Commonwealth of Pennsylvania refers to the turnpike as the Granddaddy of the Pikes, a reference to turnpikes . Milestones in the construction of the Interstate Highway System include: The initial cost estimate for the system was $ 25 billion over 12 years; it ended up costing $ 114 billion (equivalent to $ 425 billion in 2006 or $ 618 billion in 2023 ) and took 35 years. The system

15504-470: The highway passes through Banff National Park and has significant tourism. The section of Highway 1 through Banff National Park was also one of the first highways in North America to have wildlife crossing structures and fencing installed on it. After leaving the mountains it enters Calgary, where it becomes known as 16 Avenue N , a busy six-lane street with many signalized intersections. For

15656-409: The highway, where the road meets and transfers into the start of the Trans-Canada Highway. The terminus of the Trans-Canada Highway in Victoria , at the foot of Douglas Street and Dallas Road at Beacon Hill Park , is also marked by a "mile zero" monument. St. John's downtown arena, Mary Brown's Centre , was originally branded under naming rights as "Mile One Centre" in reference to the geography of

15808-454: The inefficiency of evacuating from southern Louisiana prior to Hurricane Georges ' landfall in September 1998, government officials looked towards contraflow to improve evacuation times. In Savannah, Georgia , and Charleston, South Carolina , in 1999, lanes of I-16 and I-26 were used in a contraflow configuration in anticipation of Hurricane Floyd with mixed results. In 2004, contraflow

15960-431: The last two digits match the parent route (thus, I-294 is a loop that connects at both ends to I-94 , while I-787 is a short spur route attached to I-87 ). In the numbering scheme for the primary routes, east–west highways are assigned even numbers and north–south highways are assigned odd numbers. Odd route numbers increase from west to east, and even-numbered routes increase from south to north (to avoid confusion with

16112-424: The longer Trans-Canada Highway route. Another example is that much long-distance traffic between Western and Eastern Canada will drive south into the United States and use the Interstate Highway System, rather than the Trans-Canada Highway through Northern Ontario . The main Trans-Canada Highway is uniformly designated as Highway 1 across the four western provinces. The British Columbia section of Highway 1

16264-417: The main TCH line. The TCH then follows Autoroute 25 southbound, crossing the St. Lawrence River through the 6-lane Louis-Hippolyte Lafontaine Bridge–Tunnel , and proceeds northeast on Autoroute 20 for 257 km (160 mi) to Lévis (across from Quebec City ). East of Lévis , the Trans-Canada Highway continues on Autoroute 20 following the south bank of the St. Lawrence River to

16416-439: The main Trans-Canada route is designated Highway 1 and the Yellowhead route is designated Highway 16 throughout. Prince Edward Island and Newfoundland and Labrador also designate Highway 1 as their section of the TCH, while New Brunswick uses Highway 2 (a separate important highway—albeit non-TCH—is Highway 1 in that province). East of Manitoba, the highway numbers change at each provincial boundary, or within

16568-418: The main route across Northern and Eastern Ontario, until widening out to a freeway at Arnprior, near Ottawa. In Kenora, the Trans-Canada designation includes both the main route through the city's urban core and the 33.6 km (20.9 mi) Highway 17A bypass route to the north. The existing branch from Kenora continues east for 136 km (85 mi) to Dryden . This section of highway passes through

16720-404: The mainland on a ferry. This length of the route is 234 km (145 miles), and consists of New Brunswick Highway 16, Prince Edward Island Highway 1, and Nova Scotia Highway 106. This leg of the Trans-Canada Highway sees moderately high traffic volumes and is an important tourist route. The Confederation Bridge is often viewed as an attraction in itself. Although the highway is mostly

16872-407: The mainline from Northern Ontario is via the non-TCH southern section of Highway 400, while access from Toronto to Quebec and points east is via Highway 401 (North America's busiest highway and a major national highway in itself), a short non-TCH section of Autoroute 20 , and A-30 , where the Trans-Canada is joined at A-40 just west of Montreal. From Ottawa, the Trans-Canada Highway continues as

17024-450: The mainline. Some auxiliary highways do not follow these guidelines, however. The Interstate Highway System also extends to Alaska , Hawaii , and Puerto Rico , even though they have no direct land connections to any other states or territories. However, their residents still pay federal fuel and tire taxes. The Interstates in Hawaii, all located on the most populous island of Oahu , carry

17176-446: The many non-expressway sections of the Trans-Canada Highway often form the main streets of communities, with homes and businesses directly adjacent to the Trans-Canada Highway. The Trans-Canada Highway is not always the preferred route between two cities, or even across the country. For example, the vast majority of traffic travelling between Hope and Kamloops, British Columbia, takes the Coquihalla Highway via Merritt , rather than

17328-737: The maximum speed limit is 75 mph (120 km/h) in northern Maine, varies between 50 and 70 mph (80 and 115 km/h) from southern Maine to New Jersey, and is 50 mph (80 km/h) in New York City and the District of Columbia. Currently, rural speed limits elsewhere generally range from 65 to 80 miles per hour (105 to 130 km/h). Several portions of various highways such as I-10 and I-20 in rural western Texas, I-80 in Nevada between Fernley and Winnemucca (except around Lovelock) and portions of I-15 , I-70 , I-80 , and I-84 in Utah have

17480-425: The next 293 km (182 mi) after Calgary, the Trans-Canada Highway continues as a four-lane expressway, with few stops along its route. Medicine Hat is served by a series of six interchanges, after which the Trans-Canada crosses into Saskatchewan on the way to Moose Jaw . The highway mainly travels straight as a four-lane route for most of these sections. The expressway continues 79 km (49 mi) east to

17632-451: The non-freeway sections are subject to frequent closures due to crashes, especially in winter. It is considered a dangerous route due to its extensive outdated sections of winding two-lane highway. Because this section of the highway passes through a largely undeveloped and forested area, collisions with animals are a common cause of crashes. As recently as 2022, Sault Ste. Marie's local government has asked for Highway 17 to be expanded north of

17784-404: The number of fatalities on the Interstate Highway System amounted to more than 5,000 people annually, with nearly 5,600 fatalities in 2022. The United States government's efforts to construct a national network of highways began on an ad hoc basis with the passage of the Federal Aid Road Act of 1916 , which provided $ 75 million over a five-year period for matching funds to the states for

17936-407: The older United States Numbered Highway System . As a result, highway construction standards vary considerably among provinces and cities. In much of British Columbia, Ontario, Prince Edward Island, and Newfoundland and Labrador, the Trans-Canada Highway system is still in its original two-lane state. British Columbia is actively working on converting its section of Highway 1 east of Kamloops to

18088-576: The only true freeway sections of the route are along the Regina Bypass, in Medicine Hat, and between Calgary and Banff, the whole highway is largely stoplight-free, with "split" at-grade intersections forming the vast majority of the junctions. The speed limit is restricted to 90 km/h (56 mph) through national parks in Canada, including Banff National Park. East of Banff, traffic on most of Highway 1 through Alberta, Saskatchewan, and Manitoba

18240-561: The original Interstate Highway System was proclaimed complete in 1992, despite deviations from the original 1956 plan and several stretches that did not fully conform with federal standards . The construction of the Interstate Highway System cost approximately $ 114 billion (equivalent to $ 618 billion in 2023). The system has continued to expand and grow as additional federal funding has provided for new routes to be added, and many future Interstate Highways are currently either being planned or under construction. Though heavily funded by

18392-633: The planning phase between them. In 1966, the FHWA designated the entire Interstate Highway System as part of the larger Pan-American Highway System, and at least two proposed Interstate expansions were initiated to help trade with Canada and Mexico spurred by the North American Free Trade Agreement (NAFTA). Long-term plans for I-69 , which currently exists in several separate completed segments (the largest of which are in Indiana and Texas ),

18544-411: The prefix H . There are three one-digit routes in the state ( H-1 , H-2 , and H-3 ) and one auxiliary route ( H-201 ). These Interstates connect several military and naval bases together, as well as the important communities spread across Oahu, and especially within the urban core of Honolulu . Both Alaska and Puerto Rico also have public highways that receive 90 percent of their funding from

18696-423: The present, with the current goal of rebuilding the freeway to a minimum six-lane layout from Langley to Abbotsford by 2025. Canadian French In 2011, the total number of native French speakers in Canada was around 7.3 million (22% of the entire population), while another 2 million spoke it as a second language. At the federal level, it has official status alongside English . At the provincial level, French

18848-533: The protests of the region that the route served a provincial purpose, a second round of transfers saw Highway 17 within Ottawa downloaded entirely on January 1, 1998, adding an additional 12.8 km (8.0 mi) to the length of Regional Road 174. The highway was also downloaded within the United Counties of Prescott and Russell , where it was redesignated as County Road 17. The result of these transfers

19000-546: The proximity to Quebec and/or French Canadian influence on any given region. In New Brunswick, all government services must be available in both official languages. Quebec French is spoken in Quebec. Closely related varieties are spoken by Francophone communities in Ontario, Western Canada and the New England region of the United States, differing only from Quebec French primarily by their greater linguistic conservatism . The term Laurentian French has limited applications as

19152-415: The region. The usage of miles instead of kilometres at both designations dates back to when the Trans-Canada Highway was completed in 1962, prior to metrication in Canada . The Yellowhead Highway is a 2,859-kilometre (1,777 mi) highway in Western Canada, running from Masset, British Columbia , to where it intersects Highway 1 (Trans-Canada Highway) just west of Portage la Prairie, Manitoba . It

19304-555: The remaining 8.5 km (5.3 mi) of freeway under construction, with final completion targeted for 2026. Once this project is complete, the disconnected sections of Autoroute 85 will be joined, and all of Quebec's Mainline Trans-Canada Highway route will be minimum four-lane freeway standards. This will also result in the TCH becoming a continuous freeway from Arnprior, Ontario, to Lower South River, Nova Scotia . The Trans-Canada Highway crosses into New Brunswick and becomes Route 2 just northwest of Edmundston . From Edmundston,

19456-479: The route a full freeway began in the late 1990s and was completed in 2007. The 13-kilometre-long (8.1 mi) Confederation Bridge connecting PEI to New Brunswick opened in 1997. Replacing the ferry that previously serviced that route, it was hailed as a major accomplishment. In 2000 and 2001, Transport Canada considered funding an infrastructure project to have the full Trans-Canada system converted to limited-access divided highways. Although construction funding

19608-524: The route, without regard to the route number. For instance, I-190 in Massachusetts is labeled north–south, while I-195 in New Jersey is labeled east–west. Some looped Interstate routes use inner–outer directions instead of compass directions, when the use of compass directions would create ambiguity. Due to the large number of these routes, auxiliary route numbers may be repeated in different states along

19760-419: The same numbers, which is generally disallowed under highway administration guidelines. Several two-digit numbers are shared between unconnected road segments at opposite ends of the country for various reasons. Some such highways are incomplete Interstates (such as I-69 and I-74 ) and some just happen to share route designations (such as I-76 , I-84 , I‑86 , I-87 , and I-88 ). Some of these were due to

19912-503: The same roadway are signed as traveling in opposite directions; one such wrong-way concurrency is found between Wytheville and Fort Chiswell , Virginia, where I‑81 north and I‑77 south are equivalent (with that section of road traveling almost due east), as are I‑81 south and I‑77 north. Auxiliary Interstate Highways are circumferential, radial, or spur highways that principally serve urban areas . These types of Interstate Highways are given three-digit route numbers, which consist of

20064-483: The significant elevation changes along the Lake Superior route, since it is much flatter and the transit time for heavy hauling is usually the same. The area is also not well-known as a tourist destination outside of fishing tours, which are often fly-in. A much shorter 60-kilometre (37 mi) section of Highway 66 connects another northern Trans-Canada Highway route to Quebec's Highway 117 , which itself continues

20216-537: The site. In the rest of Banff National Park, much of the predecessor Highway 1 parkway was bypassed by a new two-lane route in the 1960s. The original route between Banff and Lake Louise remains as the Bow Valley Parkway and Lake Louise Drive, while a section over Kicking Horse Pass was abandoned and is now part of the Great Divide Trail . Between 1973 and 1990, the highway was twinned from Calgary to

20368-531: The ten provinces, and connects most of the country's major cities, including Vancouver , Calgary , Regina , Winnipeg , Ottawa , Montreal , Quebec City , and Fredericton . One of the main route's eight other parallel routes connects to the tenth province, Prince Edward Island . While the other parallel routes in the system are also technically part of the Trans-Canada Highway, they are usually considered either secondary routes or different highways altogether. For example, Highway 16 throughout Western Canada

20520-469: The time it was considered a major improvement to the gravel roads and ferries it replaced, it was soon believed to be insufficient to handle the growing traffic volumes. In response, several provinces began to construct realignments, freeway widenings, and twin sections of highway in response to traffic flow and safety concerns. In British Columbia's Lower Mainland, the Upper Levels Freeway alignment

20672-463: The towns along the Fraser Canyon section of the Trans-Canada Highway, since most of the travel and tourism business along the route quickly dried up when most of the traffic took the new highway. The towns continue to be largely deprived of wealth, and some are close to being abandoned. On the other hand, Merritt , located midway up the new Coquihalla highway, ended up booming, and continues to grow as

20824-490: The war, complied by submitting a detailed network of 20,000 miles (32,000 km) of interconnected primary highways—the so-called Pershing Map . A boom in road construction followed throughout the decade of the 1920s, with such projects as the New York parkway system constructed as part of a new national highway system. As automobile traffic increased, planners saw a need for such an interconnected national system to supplement

20976-459: The whole alignment of the Trans-Canada Highway through the Lower Mainland a freeway. All bypassed sections of the highway were absorbed into various urban and rural road networks. The older freeways in the Lower Mainland were largely built as a parkway design, with wide, forested medians and low overpasses (a road configuration that was common across North America at the time). After the opening of

21128-486: The winter when inclement weather can make the steep grade virtually impassable. At Sault Ste. Marie, the main route turns eastward for 291 km (181 mi) to Sudbury . The mainline route then continues east from Sudbury for 151 km (94 mi) to North Bay. The northern route rejoins the mainline here, which continues 339 km (211 mi) to Arnprior , where it widens to a freeway and becomes Highway 417 . The freeway continues to Ottawa passing through

21280-733: The world. The highway system is recognizable by its distinctive white-on-green maple leaf route markers , although there are small variations in the markers in some provinces. While by definition the Trans-Canada Highway is a highway system that has several parallel routes throughout most of the country, the term "Trans-Canada Highway" often refers to the main route that consists of Highway 1 (British Columbia, Alberta, Saskatchewan, and Manitoba), Highways 17 and 417 (Ontario), Autoroutes 40, 25, 20, and 85 (Quebec), Highway 2 (New Brunswick), Highways 104 and 105 (Nova Scotia), and Highway 1 (Newfoundland). This main route starts in Victoria and ends in St. John's , passes through nine of

21432-523: Was approved by the Trans-Canada Highway Act of 1949, with construction commencing in 1950. The highway officially opened in 1962, with the completion of the Rogers Pass section of highway between Golden and Revelstoke . This section of highway bypassed the original Big Bend Highway, the last remaining section of gravel highway on the route. Upon its original completion, the Trans-Canada Highway

21584-616: Was completed on August 30, 2007, with the new Park Bridge and Ten Mile Hill sections opening up 16 km (9.9 mi) of new four-lane highway. Other smaller four-lane widening projects on the Trans-Canada Highway in the interior of British Columbia were also built around the same time. As part of the Gateway Program , 37 km (23 mi) of congested four-lane Highway 1 freeway in Metro Vancouver were widened to an eight-lane buildout starting in 2012. This project continues into

21736-413: Was composed of sections from pre-existing provincial highways, it is unlikely that the Trans-Canada Highway will ever have a uniform designation across the whole country. Unlike the Interstate Highway System in the United States, the Trans-Canada Highway system has no national construction standard, and it was originally built mostly as a two-lane highway with few multi-lane freeway sections, similar to

21888-541: Was employed ahead of Hurricane Charley in the Tampa, Florida area and on the Gulf Coast before the landfall of Hurricane Ivan ; however, evacuation times there were no better than previous evacuation operations. Engineers began to apply lessons learned from the analysis of prior contraflow operations, including limiting exits, removing troopers (to keep traffic flowing instead of having drivers stop for directions), and improving

22040-399: Was largely open by the late 1930s, it was not fully completed until 1951 (in large part due to World War II interrupting construction). However, despite the gap, vehicles could still cross the county by getting ferried around the relatively short section of incomplete highway by either rail or water, and Highway 11 was completed to Hearst from the east by 1937 and Nipigon by 1943. The system

22192-611: Was made available to some provinces for portions of the system, the federal government ultimately decided to not pursue a comprehensive limited-access highway conversion. Opposition to funding the limited-access widening was due to low traffic levels on parts of the Trans-Canada Highway. Prior to the start of the Great Recession in 2008, the highway underwent some changes through the Rocky Mountains from Banff National Park to Golden , British Columbia. A major piece of this project

22344-467: Was opened in 1960 with the completion of the Second Narrows Crossing , which allowed the Trans-Canada Highway to bypass downtown Vancouver's streets and the narrow Lions Gate Bridge . The four-lane Upper Levels Freeway was relatively-crudely constructed, with narrow lanes, low overpasses, and no proper merge ramps. It remains in this state in the present day. Between 1962 and 1964, Highway 1

22496-422: Was proclaimed complete in 1992, but two of the original Interstates— I-95 and I-70 —were not continuous: both of these discontinuities were due to local opposition, which blocked efforts to build the necessary connections to fully complete the system. I-95 was made a continuous freeway in 2018, and thus I-70 remains the only original Interstate with a discontinuity. I-95 was discontinuous in New Jersey because of

22648-546: Was rerouted onto a new four-lane freeway bypass between Vancouver and Chilliwack . This section of highway was originally part of British Columbia's own 400 series of highways , until the designation was replaced by Highway 1. A freeway alignment on the Trans-Canada Highway between Chilliwack and Hope opened in 1986. The opening of the Cassiar Tunnel in 1990 bypassed the last sets of signal lights in Vancouver, rendering

22800-494: Was serving as Supreme Commander of Allied Forces in Europe during World War II . In 1954, Eisenhower appointed General Lucius D. Clay to head a committee charged with proposing an interstate highway system plan. Summing up motivations for the construction of such a system, Clay stated, It was evident we needed better highways. We needed them for safety, to accommodate more automobiles. We needed them for defense purposes, if that should ever be necessary. And we needed them for

22952-466: Was the longest uninterrupted highway in the world. Construction on other legs continued until 1971, when the last gap on Highway 16 was completed in the Upper Fraser Valley east of Prince George , at which point the highway network was considered complete. When the Trans-Canada Highway first opened, it was almost exclusively a two-lane route for its whole length across the country. While at

23104-478: Was the truncation of Highway 17 at the western end of Highway 417. 1990 saw the opening of the two-lane Kenora Bypass , providing through traffic with a way to avoid the congested town. Starting in the 1960s, Quebec began to build its Autoroute network. Many sections of Trans-Canada Highway were widened to freeway standards during that era of highway construction. Starting in 1987, New Brunswick began to widen its section of TCH to four lanes. Work to make
